How could I protect my paypal form

I'm new to the paypal API, I read an article today that says : It's very simple for a bad guy to change the value of inputs in the paypal form (like the amount).

So instead of putting my code in the html markup, I decided to bring it via the ajax as the following :

<div id="result"></div>


$.post({'action.php', {}, function(data)
{
   $('#result').html(data);

}, , 'html');

in my page action.php, I put this simple code :

<?php
     echo '<input type="hidden" name="amount" value="99">';
?>

My question is : In this case, could bad folks change the value of this input ?

Thanks

Yes, of course they could.

Using the web developer tools that come with the browser, or with firebug, they can change values of hidden fields or of JavaScript values before the AJAX call.

You are adding a very thin layer of obfuscation that anyone with web development experience can easily get through.
